Since Sirga has fully recovered from her injuries and has begun to grow into her adulthood, Gruener decided that it was best for her to live in the wild.

However, this meant that he first had to coach Sirga how to hunt in order for the lion to survive in the woods and there is nothing more adorable than seeing Gruener acted like a parent to Sirga and taught her hunting skills!

Gruener spent hours teaching Sirga stalking and killing skills, skills that are supposedly taught by adult lions to their cubs.

Since Sirga has never had any adult lions in her life, Gruener takes the role.

Their close relationship is portrayed in the six-part series, “Lionheart” which premiered on September 16, 2016 on Animal Planet channel.
